The 37-year-old talk show host joined the guys – Anthony Kiedis, Flea, Josh Klinghoffer and Chad Smith – as they sang a bunch of their hits including “Give It Away Now,” “Under the Bridge,” “Californication,” new single “Dark Necessities” and a song from the musical Oliver!

James and Anthony also end up in a wrestling match after the two have a conversation about Greco-Roman-style wrestling.

Anthony Kiedis puts his tattoos and muscular physique on display while going shirtless for a day at the beach on Monday (December 28) in Hawaii.

The 55-year-old Red Hot Chili Peppers lead vocalist spent some quality time on the beach with his son Everly Bear (not pictured) during their holiday vacation.

Anthony recently opened up about working with producer Danger Mouse on the Red Hot Chili Peppers 11th studio album.

“We’ve been writing new music for the last year, and we’ve written some songs that I feel are as good as any songs we’ve ever written,” Anthony told Rolling Stone. “We’re just dying to play the new songs — but we can’t, because every single human has a recording device on them at all times.”

“He’s very good about coming up with super-modern ideas, but he’ll also touch on the acoustic guitar in the control room and strip the song down to its acoustic essentials,” Anthony added about working with Mouse. “Which is a beautiful place to be.”
